DANIEL PNMORRELL, OF SOUTH NORVALK, CONNECTICUT.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 257,048, dated April25, 1882.

Application filed March 25, 1882.

To all whom it may concern Be it known that I, DANIEL P. MORRELL, ofSouth Norwalk, Connecticut, have invented an Improvement; in Sash Locksand Fasteners, of which the following is a clear, full, and exactdescription, reference being had to the accompanying drawings, making apart of this specification, in which- Figure 1 is a perspective view ofa sash-fastener with my improvements attached. Fig.2 is a plan view ofthe same with the plate removed. Fig. 3 is the same with the boltsremoved. Fig. 4 is a view of the bolts reversed. Fig. 5 shows thepositions of the cam-flanges against the stops on the bolts.

My invention has for its object to lock and secure both sashes of awindow in any desired position; and it consists of a combination, ofdevices hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, 1 willproceed to describe the exact manner in which I have carried it out.

In the drawings, A represents the case of my fastener, which is securedby means .of screws on the upper rail of the lower sash in such aposition as when the bolts are thrown they will be brought in closecontact, one bolt with the casing of the window and the other with uppersash-rail.

On the face of the plate B, I secure the stud I), provided with a femalescrew in its end to receive the screw C, which holds the plate a inposition on the case. Over the stud b fits the sleeve D, formed on thelever or handle E, thus constituting the stud the fulcrum of the lever.On the inner end of the lever, and around the sleeve D, is formed aplate, (1-, provided with the two cam-flanges e e of peculiarconstruction, as shown in Fig. 3. The outer ends of these flanges, ifextended, would evidently pass each other and would not meet. Thepurpose of this construction will be hereinafter explained.

On the plate B are the studs F, G, and H, forming guides for the bolts Fand G. Between the studs F and G slides the bolt F for locking againstthe window-casing, and which is bifurcated that it may straddle thewindowcord in reaching the frame. The inner end of this bolt is providedon its under side with a (No model.)

projeotion,f, which fits over the cam-flange e, and .by which means thebolt is thrown or withdrawn when the cam is moved by the lever-arm E.

On the rear of the bolt, and also on its under side, I form the stop Ito catch the outer end of the cam-flange e, and thereby arrest themovement of the lever-arm E to prevent the lever from coming in contactwith the stud F, which might have a tendency to damage the stud orloosen the screws securing the fastener to the window. Between the studsG and H slides the bolt G, provided with a projection, f, on its rearand under side fitting over the flange e, by which the bolt is thrown orretracted, according to the movement of the lever-arm E. When the boltshave been thrown out asfar as desired the outer end of the camflange 0comes in contact with the stop I, which arrests the swinging movement ofthe leverarm E and prevents it pressing against stud F, thereby avoidingdanger of damaging the stud.

From this description of my invention it is evident that by a movementof the lever-arm E the cam -flanges c 6 will simultaneously throw orretract the bolts F and G at right angles to'each other, and by theprojections f f acting as stops against the flanges e e the motion ofthe lever-arm E is controlled within .any desired limits, and by meansof the lever the bolts can be pressed against the windowframe and thelower rail of the upper sash sufliciently tight to lock both sashes inany desired position.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A sash-fastener constructed as described, consisting of the case A,provided with stud b, and the lever-arm E, provided with a sleeve, D,and'the cam-flanges e e, in combination with bolt F, provided with aprojection, f, and stop I, and the bolt G, provided with a projectionand stop, f, all constructed to operate substantially as and for purposeherein set forth.

DANIEL P. MORRELL.
